NON-PUNCTURABLE CYCLE-TIRE.

SPECIFICATION forming part of Letters Patent No. 600,340, dated March 8, 1898.

Application filed November 30,1897. Serial No. 660,256. (No model.)

To all whom it may concern:

Be it known that we, JOHN THOMSON, electrical engineer, residing at 31 J oppa, by Porto Bello,and GEORGE GIBB, artist, residing at 222 High street, Porto Bello, in the county of Mid- Lothian, Scotland, subjects of the Queen of the United Kingdom of Great Britain and Ireland, have invented Improvements in or Relating to Cycle and other Tires to Prevent Puncturing and to Obtain other Advantages, of which the following is a specification.

This invention relates to improvements in cycle and other tires; and it consists in placing between the inside of the cover and the outside of the inner air-tube a metallic band composed or constructed of short lengths ofhighly tempered and polished or nickeled steel tape which are interlaced or plaited together to form a band of the required width to cover the whole of the puncturable surface of the inner air-tube, thereby effectually preventing the puncturing of said tires. In addition to the eifect of the said construction of steel band in preventing the puncturing of the inner tube it has also a considerable amount of spring when placed around the fully-inflated tube thereby increasing the resiliency and buoyancy of the wheel.

In the drawings, Figure 1 is a view of a portion of a metallic band, showing the face which is presented to the outer cover. Fig. 2 is an under view of the same portion, showing the face which is presented to the air-tube.

Referring to the said drawings, the steel tape, which may be, say, three-eighths of an inch wide and, say, a hundredth part of an inch thick, is cut into lengths A, say three and one-fourth inches long. They are interlaced at an angle of, say, forty-five degrees (more or less) and in a ratio of, say, five lengths to every three inches in alternate directions.

The ends a of the said pieces of steel tape are pivoted or bound by means of eyelets B, rivets, or other convenient means, the arrangement being such as to secure the ends, while allowing the plaited or braided band to have a certain amount of elasticity longitudinally. The sharp edges of the steel tape are protected by means of a backing or binding of broad cotton tape 0 or a band of other material, solutioned or otherwise, secured to the steel, the said band overlapping for a distance of, say, three-eighths of an inch on both sides of the outer face of the metallic band.

In order to effect the punching of the steel for the purpose of inserting the eyelets B, the ends of the pieces of steel are tempered acoordingly.

The ends of the band may be joined by being overlapped, but we may make the band so that it is endless if found more convenient.

We desire it to be understood that we do not limit ourselves to the precise length of strips shown, as it is obvious that they may be varied either Way without departing from the scope of our invention.

WVe claiin A metallic band for insertion between the air-tube and the outer cover of cycle and other tires, composed of strips of highly-tempered steel interlaced or plaited together to the desired breadth, the ends of which strips are pivoted or bound to each other by eyelets or rivets; and a cotton or other backing or binding secured thereto, whereby the tire is prevented from being punctured and resiliency obtained, as described and shown.
